However Perl6 will need it for another purpose, i.e. for "pointy subs", which may be a better choice especially from the huffmanization point of view. Also, do you imagine something like

$bar ->= nextitem;
[download]

or

@newstuff = map { ->method } @stuff;
[download]

?!?

Speaking of pointy subs and of their parameters, I find it to be quite interesting that the syntax resembles much that of my old faithful HP-28s pocket calculator (HP48*'s one should be practically identical), which happen to be an entirely coincidental fact, as Larry Wall himslef clarified in Re: Q: re C<< -> >>.
